[0043] The technical solutions of the present application will be further described in detail below in combination with the drawings in the specification and specific embodiments.

[0044] The present application designs a semi-automatic handheld pepper anti-lodging knotting fixing device, aiming to solve the problem of pepper seedling lodging in the process of pepper planting, and to reduce the labor intensity of the grower and improve the production efficiency. The knotting fixing device divides the operation process into three parts: bundling pepper seedlings, positioning transmission and knotting, to realize efficient and accurate operation. In the part of bundling pepper seedlings, a device carrying knotting rope is designed, which can realize the bundling of pepper seedlings and bamboo poles through the movement of the rotating arm.

[0045] The transmission part is the core of the whole knotting fixing device, which adopts an advanced gear train structure to realize accurate control of the knotting fixing device part.

[0046] Through the switch at the handle, the grower can conveniently control the driving and forward and reverse rotation of the two motors, thereby realizing accurate control of the rotating arm and the knotting fixing device part, so that the knotting fixing device has the functions of rotation and swing.

[0047] AsFigure 1 As shown in the figure, 1 is a rope feeding mechanism, 2 is a knot fixing device for performing knotting, 3 is a rotating disc for transmission and distribution, and 4 is a hand-held handle.

[0048] The transmission mode of the gear train assembly of the present application is as shown in the figure. Figure 4 As shown in the figure, the first spur gear 5 is engaged with the gear ring 6. The second spur gear 6' is engaged with the third spur gear 8.

[0049] The first bevel gear 6'' is engaged with the second bevel gear 7.

[0050] The first spur gear 5 is a driving wheel driven by the first motor, and the second spur gear 6' is a driven wheel.

[0051] The first bevel gear 6'' is an intermittent bevel gear, which drives the knotting beak to swing; the second spur gear 6' drives the third spur gear 8 to rotate, i.e. drives the knot fixing device to rotate.

[0052] The gear ring 6, the second spur gear 6' and the first bevel gear 6'' are fixedly connected together, which drives the swing of the knotting beak and the intermittent rotation of the knot fixing device itself, and performs periodic continuous knotting.

[0053] The knotting beak comprises a beak upper lip, a beak lower lip and a limiting cam 9, wherein the beak upper lip and the beak lower lip are hingedly connected and connected through a torsional spring, and under normal circumstances, the beak upper lip and the beak lower lip are in a closed state under the action of the torsional spring; in the knotting process, the knotting beak first hooks the knotting rope for one round of winding through the gear train assembly, during the rotation, when the beak lower lip of the knotting beak rotates to the limiting cam, the beak lower lip can contact the limiting cam and overcome the elastic force of the torsional spring, so that the beak upper lip and the beak lower lip are opened, and after rotating through the limiting cam, the beak upper lip and the beak lower lip are closed again under the action of the torsional spring, thereby biting the knotting rope, and then the knotting beak swings upward by a certain angle to realize rope release, forming an alpha-shaped knot.

[0054] As a preferred embodiment of the technical scheme of the present application, a rack is arranged on the mounting seat, a motor mounting seat for mounting the first motor is extended from one side of the lower part of the rack, and an axle hole for rotationally supporting the third axle is arranged in the middle part of the rack.

[0055] As a preferred embodiment of the technical scheme of the present application, the rope feeding mechanism comprises a rope feeding crank and a second motor, the top of the rack is used for mounting the second motor, a fourth spur gear is arranged on the driving shaft of the second motor, and a fifth spur gear engaged with the fourth spur gear is arranged at one end of the rope feeding crank.

[0056] As a preferred embodiment of the technical scheme of the present application, the limiting cam is fixed on the sleeve, and the cross section of the sleeve is rectangular, and one side of the sleeve is in abutment with the frame. Because the sleeve is a cuboid structure, it can only rotate along the contact surface of the frame, and cannot rotate around the second wheel shaft, and therefore the limiting cam cannot rotate around the second wheel shaft.

[0057] As a preferred embodiment of the technical scheme of the present application, the other end of the rope feeding crank is provided with a fixing hole for fixing one end of the knotting rope.

[0058] As a preferred embodiment of the technical scheme of the present application, a second elastic member is arranged between the knotting beak and the frame, and the relative position between the sleeve and the frame is ensured by the second elastic member, and the second elastic member is also used for resetting the knotting beak after the knotting beak swings upward.

[0059] The knotting method based on the semi-automatic handheld pepper knotting fixing device comprises the following steps: firstly, a rope feeding step is performed, one end of the knotting rope is fixed under the knotting beak by hand, the other end of the knotting rope is inserted into the fixing hole of the rope feeding mechanism, and the knotting rope is fed to the position of the other end of the knotting rope under the knotting beak by rotating the rope feeding crank. Figure 7 The knotting rope is fed to the position of the other end of the knotting rope under the knotting beak by rotating the rope feeding crank. Figure 7 In the next stage, the knotting beak mechanism knots the rope.

[0060] When starting knotting, the switch of the first motor is pressed, the third wheel shaft D rotates, the first gear 5 meshes with the inner gear 6, the first wheel shaft E rotates, the second gear 6' meshes with the third gear 8, the second gear 6' has two parts of B and C shown in the figure, and the rotation of the knotting beak can be controlled. Figure 4 A part of space is reserved between the parts B and C, and the knotting beak can be allowed to stay and buffer when rotating, so that the opening and closing process of the upper and lower parts of the knotting beak is more stable. In the rotating process, the lower part of the knotting beak is approximately a lever, the opening and closing of the knotting beak are controlled by controlling the trajectory of one end of the lever, the end of the lower knotting beak is in contact with the limiting cam, the end is lifted upward as the eccentricity of the limiting cam decreases, and then the lower end of the knotting beak moves downward, at this time, the upper and lower parts of the knotting beak are opened, and the rope is inserted.

[0061] As Figure 11 and Figure 12As shown, the knotting bird beak is kept closed by the action of the torsion spring, one side of the torsion spring extends through the gap of the first joint surface G on one side of the upper and lower parts of the knotting bird beak and hooks on the extended inclined surface at the lower end of the knotting bird beak, the other side of the torsion spring extends through the gap of the second joint surface H on the other side of the upper and lower parts of the knotting bird beak and hooks on the top surface at the upper end of the knotting bird beak, thus a downward force is applied to the outer extended part of the lower end of the knotting bird beak, and the closure of the knotting bird beak is ensured by the principle of lever.

[0062] When the eccentricity of the limiting cam increases, the knotting bird beak tightly closes the rope under the action of the torsion spring. Under the action of the rotation of the knotting bird beak itself, the rope between the knotting bird beak and the rope feeding crank is twisted into a loop, and then the knotting process is performed on the rope through the structural and functional characteristics of the knotting bird beak itself.

[0063] The first bevel gear 6'' has Figure 4 As shown, the A part of the bevel gear is engaged with the second bevel gear 7, which can control the swing of the knotting bird beak and restore it to the original position through the spring connected to the frame on the knotting bird beak shaft.

[0064] Through the process of swinging, the part of the rope that is caught can be released from the upper and lower pieces of the knotting bird beak.
